I think Stochastic Fairness Queuing (SFQ) algorithm is appropriate for freenet output. http://www.opalsoft.net/qos/DS-25.htm - equalize bandwidth between each actif node link - minimize delay on each link - adapt link usage when bandwidth change (due to QoS on network or saturate network) ----- Anonymous at o9_0DTuZniSf_+oDmRsonByWxsI ----- 2007.05.27 - 20:08:46GMT ----- Node A and Node B connected: - Node A has bandwidth 1000 with 15 active connections - Node B has bandwidth 5000 with 8 active connections As result, node B feels ok to send to node A datastream with seemingly fair speed of 625, but from Node A standpoint the fair level would be 67. 10x difference. So unlikely a particular QoS algorithm will have noticeable impact on overall performance/fairness, there are much more critical bandwidth control tasks to optimize. (But it should be easy to check: SFQ among other algorithms is implemented in linux, so just configure host, raise fred outgoing bandwidth limit to the sky (and make sure fred has something extra to send - like large storage, and/and/or large inserts), and try to notice any difference, preferably expressed in numbers. I am serious, please report the results if any.) On the other hand, good QoS could be useful on a host/network with freenet node sharing relatively slow internet connection with other applications/users. Unfortunatelly for outgoing traffic only. ----- ET at mj+bSV4hxRMtCj9fcwy4Ww9_3mc ----- 2007.05.28 - 07:37:39GMT ----- I use already QoS on my computer, HTB and SFQ for freenet. When freenet's bandwidth is reduce by QoS, bwlimitDelayTime and nodeAveragePingTime increase and reject requests (SUB_MAX_PING_TIME, MAX_PING_TIME and Output bandwidth liability). Problem is long time to take again normal activity, about 30 minutes after QoS give back bandwidth. -------------- next part -------------- A non-text attachment was scrubbed...
